Hi there - Good question! I picked up an Orange micro terror and it sounds killer. Has the Orange tone you are looking or and works great when plugged into the speaker on the DT25. I keep it on hand as a backup for gigs. I will say that I replaced the original DT25 speaker with a Weber blue dog. Sounds way better! The original speaker sounded so harsh and directional. Total ice pick to the forehead.

I ended up getting the micro terror and am pretty happy with it. I keep the tone between 12 and 1 and turn the gain nearly all the way up and that's my sweet tone right there. I took a few attempts at A/Bing it with the pod hd500 and dt25 but didn't really manage to get that crunch nailed yet. Got close with the p-75, a gibtone 1x12, line6 drive and two eqs but it's still not there.. possibly due to my lack of pod skills, I don't know.

Pretty pleased with the micro terror all the same!

I know what you mean about the directional icepick, but I tried the micro terror on a 2x12 with some unknown speakers and a 1x12 v30 but they sounded boxy and flat where the dt25 had bass and thump and fullness. Some of that could be the room tho.
